qemu-char: Introduce Memory driver
This driver handles in-memory chardev operations. That's, all writes
to this driver are stored in an internal buffer and it doesn't talk
to the external world in any way.
Right now it's very simple: it supports only writes. But it can be
easily extended to support more operations.
This is going to be used by the monitor's "HMP passthrough via QMP"
feature, which needs to run monitor handlers without a backing
device.
